Effects of SiC Addition on the Properties of MgO-based Castables

摘要：

　　The effects of SiC addition on physical properties and slag resistance of MgO-based castables were investigated using magnesia as the main raw and silica micropowder as binder.The result revealed that with increasing SiC addition,dried strength decreased,medium and high temperature strength first increased and then decreased and reached a maximum at 3% SiC addition.The hot modulus of rupture (HMOR) of the materials maximized at 3% SiC addition.The slag penetration resistance of the castables was improved while resistance to slag attack was deteriorated with the increase in SiC addition.The materials exhibited optimum slag resistance at 3% SiC additions.
